I’m sorry if this is not what you want to hear, but I’ll give my perspective anyway.
Why do you care about getting “back in your industry/career”? Yeah you did it previously, but is it really what makes you happy?
When you have goals, you always think “once I reach this, everything will be better”. In my experience and with everyone I ever talked with, this was never the lasting case. Reaching some nice goal gave satisfaction for days or sometimes even weeks or months, but never longer. Then it was back to dissatisfaction and another goal.
The common path frequently described out of depression is getting back into the groove of setting goals, following them, not being satisfied, setting another goal, repeat. This is not how I got out of my depression and also not a good life.
I don’t think it’s important that you reach your goal of getting back in your industry or whatever. I think it’s important that you’re fine with not reaching it. I think it’s important to recognize that you can be happy and satisfied right where you are, exactly with what you have.
What is “better in general”? I don’t particularly mind the human species going extinct, it’s unlikely there’ll be no life left over. No one knows the nature of the universe.
In any case, it’s incredibly unlikely we’ll go extinct anytime soon. Maybe climate change etc causes extreme loss of life, but humans are so adaptive, some will surely survive.
No one can even define “enlightenment” either. Maybe we already are, maybe such a thing doesn’t exist. Currently, it’s just a story element.
